The object of the game "Sharks!" is to get the highest
possible score, by steering the swimmer across the sea from
bottom left to the bay at the top right, without being eaten
by sharks on the way! Fortunately this swimmer has three
extra lives (as shown by the red rectangles at top left).

Use the arrow keys (either set
on your keyboard, whichever works best for you) to steer
the swimmer and avoid the sharks. You can go forwards, left,
right and even backwards. For continuous motion hold the
key down.

Every time you make it across safely, you get another
50 points. However, every time your score increases by another
100 points, another shark will appear! There is NO limit
to the number of sharks, unfortunately, so just remember
you only have four swimmers.
